Change SSH Version

I have 2 basic switches, which are using ssh v1.5 and the need for change to V2 for a monitoring tool can connect, if I change the version during office hours, will it regenerate keys RSA etc? or this will be done on the fly?

No new keys or restart required. Just enter "ip ssh version 2" on the configuration mode and save.

All new connections will be V2 (assuming that the customer who connects is capable - otherwise their connections will be refused).

I put on my deployments and have yet to see a problem with it.

  • SSH version pix 6.3.3 is the name of user pix, you can connect to?

    I test the SSH version 1 connections in a 515 6.3.3 I configuration of usernames within the pix and ssh allows connections via running ip address. THS problem is I can only connect to the PIX via the username "pix" and it will only allow one connection at a time.

    Does anyone know why not accept logings via SSH using user names defined in the device?

    Thanks in advance. Mike

    Enter the commands 'aaa-server protocol LOCAL local' and 'ssh LOCAL console aaa authentication. "

    You will then be able to connect using the local usernames on the Pix.

  • Change the version of OS W2k > W2k sp4

    Hello again,

    Unless I forgot something, there is a gap in the documentation to change the version of the operating system of a virtual computer. The documentation talking about changing the version of the Virtual Machine, but it seems that it's the version of the workstation on which the virtual machine is installed (or so I'm building the question in my mind as a rookie without much familiarity with the terminology) or the upgrade of the OS, such as, for example, from W98 to W2k. For beginners with workstation that maintains an operating system Virtual Machine, as would be the case I think of any installation Windows 2000 disk, this can be confusing and there is a lot of fear and trembling where a quick note would facilitate the spirit. There is no option in the original configuration to select Windows 2000 Pro sp4. The question of the installation of updates to SBS VM seems to have been spent past. So:

    I seek confirmation that upgrade the operating system of Windows 2000 Pro for Windows 2000 Pro SP4, all that is at issue feed on the W2k VM, inserting and executing the update disc. Is this correct? Y at - it a new update of the tools?

    No problem - and you don't have to do anything to "close the issue."  Marking the answered question supports this.

  • Is it possible to change the version of a virtual computer hardware?

    Is it possible to change the version of a 7 to 4 virtual computer hardware?

    I tried following the steps that worked for me...

    1. uninstall VM tools.

    2. unregister the virtual machine to the host/vc

    3. edit the VMX and redefine the hardware version on 4. (Do not forget... VMX file Edition is not a supported option).

    4 register the virtual machine to the host/VC

    Again, I would even using converter to downgrade the HW version.

  • Can change SWF version improve performance?

    Are there performance improvements in each new Flash Player? And if you also have set a value update the swf version?

    Update of the Flash Player plugin, you will get the performance improvements. But if you change the version of publication only - this will not affect the performance. Limitation of release version affects only have availability.

    So if you publish your swf for player 10.3, but you will have 11.7 plugin - you get the plugin performance 11.7.

    But if your computer has a Board old plugin (10.3 for example) - you will get the performance only 10.3. Also you can't get new features.

  • How can I change the Version Code in Flash Android from the Android market app settings?

    I recently tried to update my app on the Android app market and when I downloaded it I got the following message:

    "News of the apk (1000000) VersionCode already exists."

    In Flash Adnroid settings I changed the version label, but that did not help.

    So I have two questions:

    1. How can I change the Version code in Flash Android settings? I changed the version number and the version label, but it does not work.
    2. What is the difference between the version number and version label?

    1.1.0

    That should fix it, you must download the wrong file. I got this error before, by simply changing the flash version number and reexporting solves the problem. Flash can sometimes reroute your destination the exit .apk file folder, when your double apk download check that it has been created when you think it is, best way to do so is to publish and then transfer it, and after download be sure that it has been created a minute ago or so not on 30 March. Also try without the version label, it would be in conflict with something.
